PRTABL VULCANIZING DEVICE.

To all whom t may concern:

Be it known that I, ARTHUR B. Low, a citizen of the United States, residing in the city and countyof Denver and State of Colorado, have invented certain new and useful Improvements in Portable Vulcanizing Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawings, and to the characters of reference marked thereon,

f v which form a part of this specification.l

My invention relates to a portable vulcanizing device of the general character set forth-in my previous Patent No. 1,163,629, dated December 7, 1915, and designated a portable vulcanizing package.

My object isin the present application to cover specifically a construction in which the pan or receptacle for the combustible or heat-producing element, shall be connected with the clamp in such a manner that it shall properly coperate with the patch or the article to be mended or vulcanizedor both, during the vulcanizing operation. It is evident that in a construction of this class,

the receptacle for the fuel or heat-generatingor producing substance should be of such character that it may be employed lfor 'an indefinite number of vulcanizing roperations. Hence, the pan or receptacle or holder for the combustible or heat-generating substance should be constructed with this idea in view.

In this application the invention will be described moreA particularly for use in applying a patch to the inner tube of a pneu-- matic tire though it is evident that the clamp and the fuel'receptacle carried thereby may be employed in other relations. As illustrated and in the specific form to which this application will be more particularly directed, the pan or receptacle or holder for the combustible or heat-producing element, is connected in swiveledrelation with the lower extremity of the screw of the clamp, so 'that as the mrew is turned in the proper direction, the lower surface of the pan or receptacle containing the combustible or heat-generating element or substance, shall press upon the patch or upon any other article ywhich it may be desired to subject to Specification of Letters Patent. Patent June 13, 1916. Application filed January 12, 1916. serial No. 71,780. y

The patch may be applied to the lower survulcanizing act, the manner in which it is connected with the pan should be such that `the pan may release itself upon reversing canizing act.

Having briefly outlined my present improvement and in a general way indicated thefunction to be subserved thereby, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrate-d an embodiment thereof. 'y

In this drawing,-Figure 1 is a side elevation of the invention. Fig. 2 is a section taken on the line 2-2, Fig. 1, looking downwardly or in the direction of the arrow. Fig. 3 is a side elevation partly in section illustrating the use of the vulcanizing device in applying a patch to the inner tube of a pneumatic tire, or other similar article. Fig. L is a fragmentary view partly in section illustrating the device used with a liquid combustible element, and shows a cover employed to extinguish the fire or flame atthe close of the vulcanizing act while there is still a quantity of unused liquid. Fig. -5 is a side elevation partly in section showing a slightly modified form of construction. Fig. 6 is a ViewA showing still another modification. Fig. 7 is a section taken on the line 7 7, Fig. 6, looking downwardly or in the direction of the arrow. Fig. 8 isa top plan view showing a pan equipped with a coil connected with a source of electricity for-heating purposes.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a clamp having an approximately V-shaped body'member composed of upper and lower arms 6 and 7 connected by a bend 8. The free extremity of the arm 7 merges into a relatively thin expanded part 9 which, as illusthe screw after the performance of the vultrated in Figs. 1 to 5 inclusive, of the drawing, is disk-shaped though it is evident that the particular shape or outline of this part is not material and that it may vary as desired or as the particular use for which it is intended, may dictate or require. To the upper surface of the disk 9 is applied a layer 10 of some suitable non-heat-conducting substance, since it is desirable to conserve the heat as far as possible. 4

To the forward or free end of the arm 6 of the clamp is applied a screw 12 which is threaded into an opening formed in the adjacent end-@of the clamp. The upper end of this screw is fashioned vas shown at 13 to facilitate manipulation while to its lower end s swiveled as shown at 14, a pan or receptacle l5k adapted to receive a combustible or heat-generating element. |As shown in the drawing, this pan consists of a bowshaped upper part 16- to whose extremities are secured by rivets or other suitable fastening devices Ll,the body 17 of the pan or ref'v ceptacle. It is preferred that the body of the pan be rigidly secured at the points 4 to the bow-shaped member 16 though if for any reason it may be desired, the pan may be pivotally connected with the bow-shaped arm. The swiveled connection '14 between the screw and the pan, should be of such character that the screw may turn'freely when the. panl is stationary.

In the form of construction shown in Fig. 4 a cover or lid 18 is illustrated, and is readily removable from the pan, its only function ,being to cover the top of the pan for the purpose of extinguishing the iiame at the close of the vulcanizing act when liquid or otherpmaterial 19 is employed, the quantity in the pan being greater than is necessary for a single vulcanizing act.

In the form of construction shown in' Fig. 5, the pan which I will designate by the numeral 20, is of a slightly modified form of construction and is-adapted more particularly for use with a liquider-semiliquid combustible element. the top of the pan is partly closed by a hood 21 having perforations 22 to supply the ,necessary air for purposes of combustion.

This hood is brazed or otherwise suitably secured to the body 23 of the pan so that the two parts 21 and 23 are' permanently con-f nected to form a unitary structure. The screw 12 has a swiveled connection 24; with the hood of the pan, and coperates with' this form of pan in the same manner as in the previously described form of construc-` conducting layer 27. The three screws 12 of the frame, members 25, have .their lower extremities respectively swiveled tobowshaped members 28 whichare all secured as vshown at 29,'to a'relatively long pan 30. This construction is adapted for use in applying a relatively long patch, or lin per- In this casev forming the vulcani-zing act on a relatively large surface area. f

From the foregoing descriptlon the use .of my improved vulcanizing device will be needed. Such paper may, therefore, be sold separately from lthe vulcanizing. device proper if it shall be commercially desirable. In case liquids are used, as gasolene or alcohol, they may be poured into the pan as needed. Thev pan may be fitted with a cover and solid alcohol, lime, or material which will react with'acid or liquid alcohol 'or gasolene or oil or any combustible. or .heat-producing substance whatsoever may be vplaced in the pan, and in such quantity Athat it will not be necessary to charge the pan each time itis used, since one loading of the pan may if desired serve for several vulcanizing operations. It is evident that the size or shape of the pan may be such as may be found desirable or advantageous according tothe circumstances of any particular case, or the specic use to be made of the device. As heretofore stated, it is not necessary that the vulcanizablematerial be fastened to the pan, as such may be placed on the rubber tube in position'so as to cover punctures or openings made by ripping or tearing the tube, in which event the vulcanizing device is so arranged that the pan containing the heat-generating element may be screwed to position upon the vulcanizable material or patch. v

It is evident that the pan which is xedly connected with the clamp as heretofore explained, need not directly receive the combustible or heat-producing material, since cartridges containing such material may beinserted therein. Llquids maybe inclosed in shallow pans with a cover on each pan, and these pans or holders for the heat-producing element may be placed within the an or rece tacle mounted on the clamp if esired. T ese auxiliary pans may be relled or discarded as judged best. I

Assuming that the vulcanizable element 31 (see Figs. 3 and 4) is in place, either directly upoufthe pan or upon the inner tube or other article 32 to. be mended or repaired,

the pan containing the combustible element or Vheateneratilrg substance, is moved to position y adjusting the screw or screws, so that the pan shall be in contact with the v ulother article 32 in such a manner as to vir? tually form. a `part thereof, the vulcanizing function being efficiently performed. This operation requires but a few minutes, say from five to seven minutes. Furthermore, the operation may be performed by any person no matter how unskilled he may be.

After the vulcanizing operation has been performed, if there is still a quantity of unused or heat-producing element in the pan, the flame must be smothered or otherwise extinguished or the heat otherwise checked. This may be done by dropping a cover upon or over the top of the pan (see Fig. 4), or in any other manner that may be desired. The screw or screws of the clamp will then be loosened and adjusted to raise the pan from the vulcanizable element, after which the vulcanizing device may be removed.

Attention is called to the fact that calcium carbid may be placed in the pan and when it is desired to heat the pan or heatable member, a little Water may be applied to the calcium carbid which will result in the generation of acetylene gas which may be lighted for heating purposes. Again, a resistance coil 33 may be placed in the pan and connected with a suitable source of electricity.

In the drawing 39 designates a conventional source of electricity from whose opposite poles lead electrical conductors 37 and 38 to a plug 36 which is removably applied to terminals or electrodes 34 and 35 of the coil 33.

Attention is called to the afact that the pan or heatable member has its bottom exteriorly concave in order to properly taper the outer edge of the patch and merge it into the adjacent surface of the tube 32 or other device to which the patch or vulcanlzable element is applied.

Having thus described my invention, what I claim is,- i

\ 1. A portable vulcanizing device comprising a clamp having two arms connected in operativerelation and normally occupying to each other the relation of upper and lower members, the lower member being expanded at its free extremity to form a. support, while the upper member is equipped at its outer extremity with a holder open to receive fuel in bulk for vulcanizing purposes, the said holder having a swiveled connection with the upper member and being movable toward and away from the expanded extremity of the lower member.

2. A vulcanizing device comprising a base having a seat for the article to be vulcanized, an arm supported from the base and projecting over the seat, a yoke pivotally supported from said arm, a vulcanizing bottom secured to said yoke and havinga chamber to receive a heating medium, and means for causing said yoke and vulcanizing bottom to be pressed toward the base.

3. A vulcanizing device comprising a yoke having a sheet metal vulcanizing bottom permanently attached thereto and chambered to seat a heating unit, a base, an arm supported from the base and from which said yoke is suspended, and means for causing said yoke to be pressed toward said base.

4. A vulcanizing device comprising a base, a`ring shaped member having a bail, an open pan having a thin vulcanizing bottom to seat a heating unit, means rigidly connecting said pan to said ring, and means from which said bail is suspended for moving said vulcanizing bottom toward and from the base.

In testimony whereof I affix my signature, in presence of two witnesses.
